Control apparatus and method of controlling

Abstract

A control apparatus controls an image capturing unit for which an image capturing direction is movable inputs at least one of a setting value for restricting a movable range for which the image capturing direction of an image capturing unit is movable, or a setting value for restricting a visible range for which displaying is permitted in a range capturable by moving the image capturing direction of the image capturing unit and controls one of the movable range or the visible range based on a setting value for restricting the other of the movable range and the visible range.

What is claimed is: 
     
       1. An image capturing apparatus connected to a communication network, the image capturing apparatus comprising:
 an image capturing unit with an angle of view that is changeable; and 
 a processor configured to:
 (i) cause a setting value for restricting a movable range over which an image capturing direction of the image capturing unit is movable to be received via a communication network, and 
 (ii) control, in accordance with a maximum angle of view of the image capturing unit and the movable range as restricted by the setting value, a changing mechanism for changing the angle of view of the image capturing unit in a restricted range, the restricted range being larger than the movable range by the maximum angle of view of the image capturing unit. 
 
 
     
     
       2. The image capturing apparatus according to  claim 1 , wherein the restricted range is controlled in accordance with a maximum horizontal angle of view of the image capturing unit and a movable range in a pan direction as restricted by the setting value. 
     
     
       3. The image capturing apparatus according to  claim 1 , wherein the processor is further configured to: control the changing mechanism to change the angle of view in an overlap range of the restricted range determined in accordance with the movable range as restricted by the setting value and a former restricted range set before the setting value is received. 
     
     
       4. A method of controlling an angle of view of an image capturing apparatus, the method comprising:
 receiving via a communication network a setting value for restricting a movable range over which an image capturing direction of an image capturing unit is movable; and 
 controlling, in accordance with a maximum angle of view of the image capturing unit and the movable range as restricted by the setting value, the angle of view of the image capturing unit in a restricted range in which the angle of view is changeable, the restricted range being larger than the movable range by the maximum angle of the view of the image capturing unit. 
 
     
     
       5. The method according to  claim 4 , wherein the restricted range is controlled in accordance with a maximum horizontal angle of view of the image capturing unit and a movable range in a pan direction as restricted by the setting value. 
     
     
       6. The method according to  claim 4 , wherein the angle of view is controlled in an overlap range of the restricted range determined in accordance with the movable range as restricted by the setting value and a former restricted range set before the setting value for is received. 
     
     
       7. A non-transitory storage medium for storing a computer program for a method of controlling an angle of view of an image capturing apparatus, the method comprising:
 receiving via a communication network a setting value for restricting a movable range over which an image capturing direction of an image capturing unit is movable; and 
 controlling, in accordance with a maximum angle of view of the image capturing unit and the movable range as restricted by the setting value, the angle of view in the image capturing unit in a restricted range in which the angle of the view is changeable, the restricted range being larger than the movable range by the maximum angle of view of the image capturing unit. 
 
     
     
       8. The storage medium according to  claim 7 , wherein the restricted range is controlled in accordance with a maximum horizontal angle of view of the image capturing unit and a movable range in a pan direction as restricted by the setting value. 
     
     
       9. The storage medium according to  claim 7 , wherein
 the angle of view is controlled in an overlap range of the restricted range determined in accordance with the movable range as restricted by the setting value and a former restricted range set before the setting value is received.
